The car flipped as it derailed, but landed on its feet and doesn't appear to be damaged, Nuss said.

Officials from La Grange Fire & Rescue and Oldham County Emergency Management inspected the tank in the wee hours of the morning and could not find evidence of a leak.

Nuss said the tank is not a hazard, but now CSX is challenged with deciding the safest option for lifting the tank without breeching it.

A team of CSX safety officials and environmental experts are headed to the scene, he said.

Crews from RJ Corman, a company that specializes in re-railing locomotives and post-derailment clean up, have assembled in La Grange with multiple pieces of heavy equipment that will be used to lift other cars from the scene.

About a mile from the lumber company, nine trucks with flat bed trailers are staged to carry each of the derailed train cars.

Nuss said cleanup is expected to span several days. The tank car of hydrogen peroxide will be moved last.

CSX crews worked throughout the night to clear debris and repair the span of track involved. The cause of the derailment has not been determined.

Nuss said train traffic through Oldham County on Friday is expected to be light, as CSX is running a limited schedule.

CSX will not allow news crews and photographers to access the scene, as it is private property.

Three tractor-trailers each carrying four 50-foot sections of prefabricated railroad tracks arrived about 11 a.m. at the Northland Corporation.
